Dan is the man! Just a couple more questions, and (I hope!) I will have a firm grasp on how it all works...
The shuttle itself...is it a roller, or just a guide? Maybe a top-hat shaped roller so it can't lift out of the tracks?
What's on the front of the table to engage the catch/head; that is, to lock the table in place or guide it out to the left or right in the curved / partially upholstered tracks?
I can't help but think I'm over complicating this, since you said, "The Superiors have 2 plates on the bottom with rollers.One is like a guide and other is the pivot point", but...
I'm picturing 4 parts under the table, from front to back: 1.) a "button" to engage the catch, 2.) front roller, 3.) rear roller, and 4.) the shuttle.
